.MEANS FOR OPERATING FARE Application filed October 19,1905. $erial1lo.283,543.

To all whom it may concern: V Be it known that l, O'r'ro KUN'LZEN,subject of the King of Prussia, residing in Berlin, No. 58 lhaerstrasse,Germany, have invented an Improved Means for Operating, Fare andDistance Indicators, of which the following is a specification.

This invention relates to a device for operating the indicatingmechanism of fare and distance indicators for cabs or the like, and hasfor its object to provide a simple and inexpensive device that may bedriven fronii the axle of the vehicle by a belt or chain or othersuitable means, whereby the indicator will be positively and accuratelyoperated and a manual tampering with the register will be prevented.

in the accompanying drawings Figure 1 shows a form. of my inventionapplied to an air pump for operating the indicator mechanism and meansfor connecting the same with the axle of the vehicle; and Fig. 2 is asectional view, showing a modification.

According to the example of construction shown in Fig. 1, the red at ofthe piston which slides in the cylinder b 01' the air pump A has twoshoulders cl, (1, between which revolves a cam wheel f, provided on bothsides with the wedge-shaped cam surfaces g and 71.. This wheel f isdriven from the axle oi the vehicle in any known manner, ior instance itis fixed to the hub c of the wheel by means of a ring 1', connected withthe cam wheel f in any suitable manner. As the cam wheel f revolves thepiston in the cylinder b is drawn to the right by the cam surlace 9,while the cam surface it acts during the return movement of the piston,and insures a positive to and fro movement to actuate any suitableindicator means F. In order to avoid a binding of the cam surfaces 9 andit between the pressure surfaces or shoulders (I, (1' on the sliding rode in consequence of running awry oi the driving .wheel, it is preferableto make the cam surface It a little thinner than the surface g, so thatthe disk f has some play between the pressure surfaces (1, d.

In the "form shown in Fig. 2 a gearing consisting of Specification ofLetters Patent.

AND DISTANCE INDICATORS.

Patented Oct. 8, 1907.

ratchet wheel or and detent pawl 01 is employed instead of an air pump,to be moved by means of a pawl 0, which. is fastened with a pivot jointto the sliding rod a. This latter receives a reciprocating movement fromthe cam wheel f, or other means. On the rod (1 between a side of thecasing C and a collar 0 may be located a helical spring f in order tokeep the pressure surface 1] in Contact with the revolving wheel f,thereby avoiding the sudden jarring and jolting of the parts. Thetransmission of the revolution from the ratchet wheel a to the fareindicator can, in this example, be effected with the aid of a flexibleshaft or the like. In order to prevent the driver of the vehicle fromlifting off the pawl 0, the wheel '11 and the earn 0 are arranged in aclosed box or casing O.

In neither of the modification described is it possible to displace therod a without turning the wheel so that the stop mechanism of the fareindicator will be set in action. The slight movement which the rod mightpossibly have in consequence of the above mentioned play between thewheel f and the shoulder d is not sullicient to drive the ratchet wheela. If the contrivance is to serve for running a distance indicator,which tells the owner what distance the vehicle has covered daily, thedistance indicator is best affixed to the construction, Fig. l.

I claim. as my invention In combination with an indicator, a. cam wheeladapted to be actuated from the wheel of a vehicle, a sliding rodprovided with shoulders between which said cam wheel revolves and bymeans of which it imparts a positive to and fro movement to the rod inboth directions, and means whereby such motion is transmitted from therod to the indicator.

In witness whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.
